AppIication filed December 21, 1908. Serial No. 468,601.

To all whom it may concern:

Be it known that we, YV LLIAM F. HAR- nAUGI-I and OriARLnsF. SMITH,citizens of the United States, residing at 'Lakota, in the county ofNelson and State of North Dakota, have invented a new and usefulVegetable-Cutter, of which the following is a specification.

It is the object of the present invention to provide an improvedmechanism for cutting vegetables such as potatoes, and one of theobjects of the invention is to so construct the mechanism as to producepieces or particles of substantially uniform size, such an ar rangementof parts being particularly desirable where the mechanism is to be usedfor the purpose of cutting seed potatoes inasmuch as a minimum loss ofeyes will result as compared to the loss where such mechanism isemployed as will not act in a uniform manner on the potatoes.

In the accompanying drawings, Figure 1 is a side elevation of themechanism embodied in the invention. Fig. 2 is a perspective view indetail of a portion of one of the cutter elements, and Fig. 8 is a viewsimilar to Fig. 2 showing a portion of the other cutter elements.

The frame in which the mechanism is mounted, while it may be of anydesired form or construction, preferably includes spaced side sills 5and supporting standards 6 at the upper ends of which the said sills arearranged. I

Journaled in suitable bearings 7, preferably mounted upon the upperedges or sides of the sills 5, is a shaft 8 and fixed upon this shaftfor rotation therewith is a gear 9, the shaft being adapted to berotated through the instrumentality of a crank handle 10 also fixedthereon. The gear 9 meshes with a similar gear 11 which is fixed upon ashaft 12 in suitable bearings 13 arranged preferably upon the underedges or side sills 5, and it will be understood that rotation of theshaft 8 will result in a correspondingrotation, in the oppositedirection, of the shaft 12 and inasmuch as the gears 9 and 11 are ofequal diameter, the speed of rotation of the two shafts 8 and 12 will bethe same.

Fixed upon the shaft 8 for rotation there with is one of a pair ofcutter elements which comprise the cutting mechanism of the machine, andthis element is comprised of a pair of spaced annular knives 14 havingintegral spokes or webs l5 and transyerseintegral with the knives 14,are here shown as secured in notches 17 formed at equi-distant pointsthroughout the peripheries of the knives 14-. The knives 16 preferablyhave their cutting edges projecting beyond the peripheries of the knives14c and they Patented Jan. 18, 1910.

knives 16 which, while they may be formed also project at their endslaterally beyond 2 the said knives 14: as clearly shown in' Fig. 2 ofthe drawings. It will thus be seen that the cutter element justdescribed is comprised of annular knives and a plurality of transverseknives intersecting the cutting edges of the annular knives, and it willbe understood that any number of the knives 14 or 16 may be employedaccordingto the character of the material to be cut, The other cutterelement of the mechanism is in the form of a cylindrical drum or wheel18 which is provided or formed upon its peripheral surface with aplurality of spaced segments 19 each formed with a pair of grooves 20extending in a direction peripherally through the face thereof, thespaces between the segments resulting in transverse grooves 21.

As shown in the drawings, the knives lt and 16 of the first describedcutting element, and the grooves 20 and 21 of the second describedcutter element are so relatively positioned that upon rotation of thetwo cutting elements, in a direction toward each other, the transverseknives 16 will successively engage in the grooves 21 and the knives'l iwill engage in the corresponding grooves 20 in the segments 19 of thesecond described cutter element, so that potatoes or the like, fedbetween the two rotating elements', will be chopped or cut into piecesof substantially uniform size and shape. In

order to so direct the potatoes or the like to and that they thereforeperform, broadly speaking a cutting and" feeding function.

, 'In'cutter mechanism of the class described,

cooperating rotary cutting elements, and a hopper having its dischargeend above but in a plane between the said elements, one of the saidelements being of skeleton structure and comprising peripheral bladesand transverse blades intersecting the peripheral blades at intervals,said transverse blades projecting at their edges beyond the peripheralblades, whereby material fed to said hopper will be drawn between theelements, the other element being provided with intersecting groovesarranged to receive the cutting edges of the several blades of the firstmentioned element, said first mentioned element having its axis locatedin a plane 15 a as our own, we have hereto affixed our signa- 20 turesin the presence of two witnesses.
